| 摘 要： | 通过利用多种图像融合方法分别对航片数字化影像与SPOT5多光谱影像进行融合试验,经定量化指标评价结果表明,利用Pansharp,HPF和HIS融合方法计算后得出的影像在很大程度上保留了原多光谱影像的光谱特征,清晰度有较大提高,具有更强的解译和量测能力。

| Abstract: | In this paper, many different methods have been used to merge the digital aerial image and SPOT5 multi-spectrum image, and then the fused results have been evaluated through the calculations of some quantitative index. It shows that these results calculated by the methods of Pansharp, HPF and HIS could keep almost the spectrum characteristics of the original image, obviously be enhanced in the aspect of the image definition, and even more easily be identified and measured. |
